Carnon Downs renovation — feasibility first, drawings second
Cornish housing stock is brilliant and infuriating in equal measure. We renovate cottages, farmhouses, mid-century homes and post-war estates — opening up layouts, fixing damp, adding light and bringing the property up to a standard worth living in. In Carnon Downs, that work is shaped by the place itself — Carnon Downs is a substantial residential village south of Truro on the A39, with a significant late twentieth-century estate expansion and a popular village school, with a building stock that leans toward 1960s and 1970s estates and older cottages on the village fringe.
Carnon Downs sits in South Cornwall — covering TR3 from Devoran, Playing Place, Perranwell Station outward.

Carnon Downs Renovations — local questions answered.
- Can you renovate and extend at the same time?
- Yes, and often it's the right call — the planning, regs and disruption all happen once instead of twice. We design and price it as a single project. In Carnon Downs specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- Do I need planning permission to renovate internally?
- Usually no — except on listed buildings, where Listed Building Consent is needed for many internal alterations. We confirm the position before any wall comes down.
- How long does a renovation take?
- Single rooms in weeks, kitchens in two to three months, whole-house renovations in six to fourteen months depending on size and listed status.
- Can I live in the house during the work?
- Sometimes yes, often no. Single-room remodels and phased work can be liveable; whole-house renovations involving rewires, replumbing or floor lifting almost never are. We're honest about this at the brief.
- What about damp and old walls?
- We assess the cause first — usually rising damp myths, blocked vents, hard cement renders trapping moisture, or roofs needing attention. A breathable repair strategy fixes most of it without chemical intervention.
Local context
Why Carnon Downs is its own job.
Locally, outside Conservation Area and AONB but in close proximity to AONB to the south. Feock parish operates active input on edge-of-village sites and infill. For renovation specifically, Carnon Downs sits outside the headline designations, which usually gives a slightly more flexible starting point — but parish-level character still matters. Which is why we scope Carnon Downs projects parish-up, not template-down — the TR3 context shapes the design from day one. Whether the project is on 1960s and 1970s estates in the centre or further out toward Devoran, the renovation response is locally tuned.
Planning note
Most Cornish renovations don't need planning — but listed status, curtilage listing, Conservation Area designation and material changes can all change that picture.
What we focus on
Renovations considerations specific to Carnon Downs.
01
Older Cornish properties are often built with cob, rubble or solid granite — modern insulation strategies that work in cavity walls cause damp problems in solid construction. Breathable build-ups matter.
02
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
03
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
04
Damp in Cornish cottages is usually a moisture management problem, not a chemical injection problem — fixing the cause is cheaper long term than treating the symptom.
